Great thread, guys! The passenger side boot on my 2001 X5 4.4 just ripped open a month or so ago. After reading this thread I"m thinking about replacing the whole axle instead of messing with the grease and clips.

I found a couple of vendors on eBay offering Lifetime warranty... Don't care much about the warranty, but giving that the job is mostly labor, I'm a bit hesitant about purchasing an from eBay... The price is $100 including shipping, I think that's a bargain.

What do you guys think?
